Instead of using connectorRuntime (which is not supposed to be used by applications, undocumented), use the documented way :

http://docs.sun.com/app/docs/doc/819-3672/beamu?a=view

eitther by creating a resource that has a suffix as "__nontx" in jndi-name

or

com.sun.appserv.jdbc.DataSource ds=
   (com.sun.appserv.jdbc.DataSource)context.lookup("dataSource");
ds.getNonTxConnection();
